WorldEdit mod ,version 6.1.1,
minecraft1.8.9,
logs:http://pastebin.com/ifbzZVBe
Multiplayer and single player appear the same problem (But I can't get logs in a single game:( )
When I'm ready to place the mod blocks, it prompts the error (java.lang.IllegalArgumentException)
I use instruction is //set ID

Comment by wizjany

you can't use block IDs above 4096. it's only possible with mods such as NotEnoughIDs, which are huge hacks and don't work with worldedit.

Comment by Dark_Arc

@wizjany that's actually not true. Forge 1.8 appears to create item/block IDs above 4096. I actually don't have any modded items with IDs less than 4096.

@wizjany I tried again, Minecraft F3 + H display id 4144:11, but in fact the input id 244:7 is this block.(this id is accidentally find out)

Comment by wizjany

I believe F3+H only shows item ids in the inventory. the id in the world has to be less than 4096, the easiest way to find it is to use creative mode or /give, place the block, and use the //info tool and right click the block. that will tell you the id:data for it.
